T a/ZZ whom, it may concern.-

, Be it known that we, CLARENCE O. SIBLEY,

a resident of Perth Amboy, Middlesex county, New Jersey, and Gnonon A. L'u'rz,

a resident of New York city, borough of Brooklyn, New York, citizens of the United States, have invented. certain new and useful Improvements in Connectors for Conduits for Electric Wires, of which the following is specification. This invention relates to improved means for connecting conduits, made in two or more arts, with outlet or junction boxes or the li e, or with conduits of. tubular form; and the invention comprises the novel details of improvement that will be more fully hereinafter set forth and. then. pointed out in the claims.

Reference is to he had to the .accompanying drawings, forming parthereof, wherein-- Figure 1 is a central section showing a conduit of angular form provided. with a removable cover connected with an outlet or junction box by means of our improvements. Fig. 2 is an enlarged detail plan view of the connector. Fig. 3 is a cross-section thereof on the line 3 3 in Fig. 2 looking in the.direc- 'tion of the arrows. Fig. dis a plan view of the inside of the removable cap. Fig. 5 is a plan view of the connector attached to a con duit, 'the cap being removed. Fig. 6 is a per spective view of the connector, the cap being removed and Fig. 7 is a detail perspective view of the end oi. a conduit.

Similar numerals of reference indicate corresponding parts in the several views.

In the drawings we have shown our improved connector as applied to conduit 1 of the class made substantially in angular or channel form provided with a bottom and side walls that have opposed. grooves 1, that receive a removable cover .2, which may slide in such grooves.

Our connector is made in two main membcrs 3 4, detachably connected together, as by screws 5. The member 3 at one end is provided with asocket orti on 3, having a bottom 3* and side we ls that correspond in outline to thecontour of; the conduit l, and also has oil'set recesses 3, that receive the webs of the conduit having the opposed groove 1 whereby the end of the conduit may fit snugly within suc 1 sdcket portion of the connector member 3.

To prevent the connector from pulling oil the end of the conduit, the side walls of the recesses 3 are tapered. or conver e outwardly and. the side webs of the contuit that fit within such recesses are bent outwardly at 1 so that the flaring webs will bear against the taper walls 32 as shown. in Fig. '5. The cover member 4 of the connector fits over the flared ends 1 of the conduit, and the screws 5 keep the connector members clamped upon the ends of the conduit. The cover member 4 has a lug or projection 4, that projects into the conduit in line with the cover 2 to limit the inward movement of said cover into the connector, whereby the cover may be brought up snug against the connector. (See Figs. 1 and 3.) The opposite ends 3 of the members of the connector are tubular and are shown novided with screw-threads to receive the not 6, each member 3 4 carrying a portion of such tubular extension.

ln l ig. 1 the tubular extension 3 is shown passing through an aperture in an out.-

let or junction box 7, the not 6 clamping the bular conduits or pipes by means of threaded sleeves or other connections.

By means of our 1m rovements we are en added to connect con uits made'in angular form and also those made of two or more parts with circular holes in boxes or'other terminals or with tubular extensions therefrom or with tubular conduits or pipes, with the assurance of a rigid connection between such conduits and other parts. The connector also permits of the ready detachment oi the conduit when required and also. of proper adjustment of the wires within the upon the same. v The particular details of constiu'hlfion shown and described and the particular form of conduit illustrated for use in. connection with our connector may be varied without departing from the spirit of our invention.

Having now described our invention, what we claim is- 1. The combination of a conduit made in angular form, with a connector having a socket to receive the end of the conduit and conduit and the proper placing of tl'ie, :over

corresponding in shape to the contour of the conduit, a removable member over the socket, and tubular extension on said counector, said tl ends, a box. having a hole through which said threaded extension posses, end a nut on said threaded extension Within the be); held- .ing the connector thereto, substantially described.

2. The combination oi? a conduit provided with av removable sliding cover, with a con-- nector having a socket receiving said conduit and provided with a tubular. \tension, said connector having a big lying in the path of the cover of the conduit, substimtislly as or scribed.

3. The combination. of a. conduit. bottom, and side walls provided with opposed gl'OOVGS, and IOD'lOVz'tblB rover ioacted. in said grooves, with. a connector having it socket correspomlii'ug in, shape to the conduit and i rovidcd with in weirdly-tapering or convci mg vviills receiving the grooves on the con nit, said connector being provided with a tubular extension on the side opposite the socket, the grooves at the end of the conduit being l'lorod to cooperate with the corresponding walls of the socket, substontiaflly described.

4. The combination of a, conduit having a. bottom, and side walls provided with opposed grooves, the end portion o the webs forming such grooves being bent outwardly, and it cover removobly carried in said grooves, with :1 connector comprising a pair of mem ers, one of which has a. socket correspondi. to the conduit and recesses having tapering or converging side avails to receive the tiered. ends of said vrel'is, and means For clomping said members together, substantially described.

The combination of a conduit having a bottom and side walls provided with up posed grooves, the end portion of the webs forming such grooves being bent outwardly, and a, cover removebly carried in said grooves, with a connector comprising a pair of members, one of which has a socket corresponding to the conduit and recesses having tapering or converging side walls to receive the flared ends 0i said Webs, and means for clamping said members together, one of said members having :1 lug projecting inithe path 0! the cover, substantially as described.

6. The con'ibination of a conduit having at bottom and side Walls provider. with opposed grooves, the end portions of the webs extension having external,

having 2,

Forming such grooves being bent outwurdlv, and it cover removsbly carried in said grooves, with it connector comprising u pair of members, one oi which has a socket corre sponding to the conduit and recesses having tapering or converging side walls to receive the flared ends of said webs, means i or clmnping said members together, one of satin members having a lug projecting in: the path of the cover, said connector having it tubular extension on the side opposite said socket, subr scribed.

8. It connector comprising 2L pair of 1118111"- bor one oi which bus :1 socket having :1 bottom and side Walls extending at am tingle to the bot-tom. and I'QCPSSQS at the ends of said walls, the distance between the side wells of the recesses being greater than the distmicc between the 'lirst mentioned walls, said mem bers having a tubular extension at the end opposite the socket provided with external threads. substantially as described.

9. A connector comprising a pair ol me1nbars, one of which has :1 socket in angular form and recesses lit the open side of the socket, the dist-once between the side walls of the recesses being grenier than the width of the socket, the side walls of said recesses toporing or converging, said members lmving IL tubular extension at the opposite end, one of so id members having a lug projecting toward said socket, substantially ds described.

10. A connector for conduits comprising a pair of members, one of which is provided with it socket opening through one end having :1 bottom, and sides extending at on. angle to the bottom, the-other member having it lug projecting toward the socket in line therewith, and means to hold said members firmly united, substontiall es described.
